in the figure, the grinding device comprises a base 1, a base 2, a workbench 3, a guide rail 4, a mounting seat 5, a grinding device 6, a drill fixing seat 7, a sliding block 8, a bottom plate 9, a side plate 10, a bearing 11, a screw rod 12, a shaft 13, a transmission gear 14, a driven gear 15, a mounting block 16, a fixing groove 17, a stepping motor 18, a motor 19, a conveying belt 20, a speed reducer 21, a grinding piece 22 and a gear.

Detailed Description

Fig. 1-6 are the utility model discloses a structural schematic diagram, a step grinding machine, including base 1, base 1 top is workstation 2, and workstation 2 upper berth is equipped with guide rail 3, has mount pad 4 in the side welding of base 1, has grinding device 5 through the bolt fastening on mount pad 4, installs slider 7 on the guide rail 3, has drill bit fixing base 6 through the bolt fastening on slider 7.

This kind of step grinder, when using, the drill bit that will need the grinding is fixed on drill bit fixing base 6, drill bit fixing base 6 is the three-jaw, the four-jaw chuck, can carry out firm fixed with the drill bit, after grinding device 5 is switched on afterwards, begin work, it is that grinding device 5 carries out the back-and-forth movement along mount pad 4, polish the terminal surface of dress head, drill bit fixing base 6 passes through slider 7 and installs on guide rail 3 on workstation 2, drill bit fixing base 6 just can remove along guide rail 3 under the condition of workman's operation and remove, just so can polish around the drill bit, the three-jaw, the four-jaw chuck can rotate on drill bit fixing base 6, just can carry out full angle to the drill bit and polish.

According to the utility model discloses a further embodiment, further include, mount pad 4 comprises bottom plate 8 and curb plate 9, install bearing 10 in the curb plate 9, bearing 10's inner circle matches with lead screw 11, there is the installation piece 15 that matches in lead screw 11 screw thread at the middle part of lead screw 11, the tip of lead screw 11 is furnished with driven tooth 14 through the key, driven tooth 14 meshes with the driving gear 13 of installing on axle 12, axle 12 passes through the bearing and installs on curb plate 9, there is hollow fixed slot 16 in the curb plate 9, install step motor 17 in the fixed slot 16, gear 22 and the meshing of driving gear 13 of installation on step motor 17's the output shaft.

Step motor 17 on mount pad 4 is when circular telegram work, make gear 14 installed above that rotate, gear 14 drives driving tooth 13 and rotates, driving tooth 13 meshes with driven tooth 14, and then make driven tooth 14 rotate, at this moment because driven tooth 14 installs on lead screw 11 in, just can drive lead screw 11 and rotate, because lead screw 11 is two, installation piece 15 on lead screw 11 in the installation is fixed through bolt and grinding device 5, under fixed state, when lead screw 11 rotated in, just can promote installation piece 15 and carry out the back-and-forth movement, and then drive grinding device 5 and carry out the displacement.
